Update F# compiler on the Travis CI

[bentayloruk]

This PR uses named values on a discriminated union. This is an F# 3.1 language feature and the Travis CI server is compiling with F# 3.0, so the PR breaks the build. Is it possible to update the CI to use 3.1?

Actually I don't know. We need someone with mono knowledge. Maybe @7sharp9 can help!?

As far as I know @ovatsus uses 3.1. See: https://github.com/7sharp9/FSharp.Data/blob/master/.travis.yml

[forki]

cool. thanks

[ovatsus]

That that is building from source, which is unfortunate as builds take too long. Maybe the latest binary now would now work?

[bentayloruk]

Another reason to support it when we can, is that I added DU case value name support to UnionArgParser so we can get an even better FAKE CLI experience fsprojects/Argu#11 (comment)

I'd love to use a newer version, but don't know how.

The Travis build seems to be working now, so is this still needed? In any case, updating the mono version from 3.4.0 to 3.8.0 in .travis.yml should get you F# 3.1

[forki]

wow F# 3.1 - that sounds cool.

[bentayloruk]

I removed my 3.1 feature usage, so I don't need it in the context of this issue. I'll leave it up to @forki if he wants to close this or leave it open until the .travis.yml gets updated.

I'd love to see a PR for this.

Submitted, we can wait to see if the build goes through cleanly.
